Introduction
The EM-8661-220V Ring Launcher is used for demonstrating the
principles of electromagnetic induction and magnetic force. It is
an electrically powered projectile launcher. Using a conducting
but non-magnetic aluminum ring (included), you can show how
the alternating current in the electromagnetic coil induces an
alternating current in the aluminum ring, which produces a mag-
netic field opposed to the field of the electromagnetic coil. As a
result, the aluminum ring is pushed upward.
The optional Ring Launcher Accessory (EM-8862) includes a
heavy copper ring, a lightweight aluminum ring, a split alumi-
num ring with a gap, and a small light bulb connected to a copper
coil that can be used for more demonstrations of electromagnetic
induction and magnetic force.
